A method of connecting two or more construction elements of a building structure using a profiled wire tie ( 7 ) comprising a core from which a plurality of loosely wound helical fins extend radially along its longitudinal axis and which is formed into a point ( 8 ) at each end. The method comprises the steps of: inserting a impact spindle ( 4 ) of a power driven adaptor ( 1 ) into the chuck of a rotary hammer drill; inserting the tie ( 7 ) sideways into an open longitudinal slot ( 3 ) in the side of the adaptor ( 1 ), which concentrically aligns the tie ( 7 ) with the impact spindle ( 4 ) and provides a means by which to steady the tie ( 7 ), when holding the handle ( 2 ); driving the tie ( 7 ) into the first construction element ( 9 ) whereby the action of the rotary hammer drill transmits and imparts, via the impact spindle ( 4 ), torsional impacts to the tie ( 7 ), which is driven via a series of helical thrusts ( 11 ), to cut a spiralling penetrative thread into the first construction element ( 9 ) and sequentially into the subsequent element(s) until the tie ( 7 ) is at least flush with the surface of the near construction element ( 9 ) and is seated at its desired penetrative depth within the subsequent element(s). |
